It's been a rocky weekend for Tom Cruise, but despite the fact that Katie Holmes filed for divorce, he was back to work near Reykjavik today. Tom and his son Connor are staying in Iceland while he films additional scenes for his futuristic space project, Oblivion. The guys seem to be making the best of their time in Scandinavia, and even though Tom's busy on the set, Connor's taking advantage of the picturesque location. Connor's been sharing photos on his Instagram account of his volcano hikes, snowmobile adventures, and near-freezing glacier dives.

Tom celebrates his 50th birthday on Tuesday, but it's unlikely he'll be partying with Katie. The actor was reportedly blindsided by her decision to file for divorce and sole custody of Suri. Katie and Suri have moved out of Tom's Manhattan apartment and are rumored to be settling into a new residence.
